The Effect of Transcranial Direct Current Stimulation (tDCS) on Dyspnoea Perception, Pulmonary Function and Functional Level During COPD Exacerbation

tDCS will be applied to the dorsalateral prefrontal cortex with a current of 2 mA for 30 minutes on 3 consecutive days.

The tDCS application will be increased to 2 mA for the first 30 seconds and will be reduced to 0 mA within 30 seconds after receiving current for 15 seconds. The electrodes will remain on the patient's head for the rest of the time (30 min in total).

"Within the scope of conventional physiotherapy, respiratory control training, diaphragmatic breathing exercise, puckered lip breathing, relaxation exercises will be started 10 minutes after the start of tDCS or sham tDCS application.~While tDCS or sham tDCS application continues, 10 repetitions will be performed in order and with time for rest between exercises."
